When I decorate a class method with abc.abstractmethod, and I call it from the class (not the instance), the call is successful.

It looks like ID 5867 which was closed years ago.

This behavior is consistent with the behavior described in the documentation for `@classmethod`.

"It can be called either on the class (such as C.f()) or on an instance (such as C().f())."

In this case, it can't be called on an instance because it is abstract, but since it's a classmethod, it is still okay to call it on the class directly.

I've also posted that response on stackoverflow to your question in case others have the same confusion.
